Eaton SPD100240H4N Surge Protection Device - UL 1449
Part Number: SPD100240H4N
Quick Summary
SPD100240H4N is a surge protection device designed to shield electrical systems from transient overvoltages in industrial and commercial panels. Voltage spikes are a perennial nuisance that can cause unplanned downtime, equipment damage, and costly warranty claims. UL 1449 certification and a NEMA 4 enclosure ensure reliable protection in harsh environments and outdoor installations. The unit supports a 240V high-leg delta (4W + G) configuration on the B phase, and it integrates with Eaton's Power Xpert SPD family to streamline monitoring and maintenance. For engineers and procurement teams, this translates to predictable performance, easier compliance, and lower total cost of ownership when safeguarding critical loads.
